-A ijstill further object of -the invention'is t'o provide means for) elevating liquid from a deep well pumpavhieh has-flow'under its own, pressure, which will be durable and Jefiicient in use,- one that will be simple and easy to n anufacture and one-which can'beincorporated with a-standa-rd well casing at 1th these-and'other objects in View, the invention consists in the novelronstructmn,

arrangement and formation of parts, as will bejhereina'fter more specifically described, clain1ed, andillustratedin the aecon'ipanying drawings, in whichdrawings;

,Referring to the "drawings in detail, wherein similar reference characters desigumtc rnrrespouding parts throughout the This outlet pipe 13 extends thr'ouglr as'uitable casing yhead v15 ,exteriorly 20f the "well. The ipacker' 6; head-315, well casing 5. aridthe leasing 7: andwoutletpipe13:,define =a .gas

The! extreme upper end oftheawellucasingt is providedswiththe compressed fluid inlet! 17 andthe compressed medium is 'iLClRPtGCiitO flow into the chamber 16 and is prevented from zgoingiintQ' 'fi "bottom of the well "by the v packer 6.

.TlTBI distributor '11 embodiesna cylinder 18 which 'is 'arrangcd in spaced concen'tric rela- I tion 110";1'111Q'S6C111011I9'01113116 casing 7 and the upper and :lower enids; of the cylinder 18; is provided with flanges or heads 19*and -20-jfor =engagiug'rthe inner 'su r'itace oi the said section' Storming a! fluid pipe connecti on tl'ierewith. The upper eudotf the cylinder; 18' is provided with a-pluralityzof relatively" fine :perforations" 21;" as isthe rflan ge or liead 19.

'willumirt wt This distributor is "preferably below the F oil levelinwth-e well, and the section?) isp'rO- videdwvith "the compressed air inlet openingsQQ for permittingthe -1flOW of the compressed gasior other medium into .the chamber 23 defined by the cylinder and section 9.

The expanding medium-arsed will then .flow

through the openings; 21 in: relatively small part1cles m'to the-011 or.,water be1ng raised.

Thev gas passing through: the openings '21 i=.aoil to a certain but J is likely to form large pockets or bubbles in the oil. When the large pockets or bubbles are formed in the oil a relatively large quantity of gas is needed to lift the oil, but if the gas is mixed thoroughly into the oil to form a plurality of minute bubbles, a relatively large quantity of oil will be lifted with the gas. The mixer 12 functions to break up the gas into fine particles and to 11:0 direct the oil and mixed gas toward the axial center of the casing so as to prevent the gas from following up the side of the casing. The mixer 12 includes a plurality of spaced concavo-convex shaped disks 25 disposed in the section 8 of the casing 7 and these disks 25 are provided with the plurality of minute mixing openings 26. Any desired number of these disks 25 are provided and are held together in their desired relation by a coupling rod 27 A ring 28 can be employed for supporting the lowermost disks.

When oil is being raised, it is preferred to use a compressed gas, while if water is being raised, steam or air will serve the purpose. A suitable compressor can be mounted at the well hole for forcing the compressed fluid into the chamber 16 and a separator receives the fluid forced from the well to separate the gas from the liquid. The compressed gas is found to separate very readily from the oil and that is the prime reason in using the compressed gas with the oil.

In use of the improved liquid pumping device, the compressed medium is allowed to flow through the inlet nipple 17 as heretobefore stated down the chamber 16, through the openings 22 into the chamber 23 then into the distributor through the minute openings 21 up through the oil, through the mixer and out of the outlet pipe 13 to the separator.

From the foregoing description, it can be seen that a simple device has been provided for forcing a fluid from a well which has sufficient pressure to rise a certain distance in the well but not enough to flow from the well.

Changes in details may be made without departing from the spirit or the scope of this invention, but

lVhat I claim as new is:

5. In a well pump, a well casing, an in ner casing disposed within the well casing in spaced concentric relation thereto, a packer supporting the inner casing having fluid pipe connection with the well casing, an outlet pipe, a casing head carried by the upper end of the well casing and engaging the outlet pipe, a reducing coupling connecting the outlet pipe with the upper end of the inner casing, means for introducing a com pressed gas to the upper end of the well casing, means for permitting the flow of the gas into the lower end of the inner casing, a cylinder arranged in spaced concentric relation to the inner casing disposed in the lower end thereof, flanges connecting the opposite ends of the cylinder with the inner casing the cylinder and upper flange having a plurality of minute openings therein through which the compressed gas is adapted to flow, and a mixer arranged in the casing above the cylinder meludmg a plurality of equi-distantly spaced concaVo-convex perforated disks, and

means holding the disks in position in said inner casing.

(5. In a well pump, a well casing having an inlet adjacent its upper end for introducing compressed gas thereinto. an inner casing disposed in the well casing in spaced concentric relation thereto and having a plurality of openings adjacent its lower end, a cylinder arranged concentrically Within the lower portion of the said inner casing and having a plurality of perforations positioned above the openings in the said inner casing, and a plurality of equidistantlv spaced concavoconvex perforated disks arranged within the inner casing above the said cylinder.

7. In a well pump. the combination with a well casing having an inlet adjacent its upper end for introducing compressed gas thereinto, and an inner casing disposed within the well casing in spaced concentric relation thereto and having a plurality of openings adjacent its lower end of a cylinder arranged concentrically within the lower portion of said inner casing, flanges carried by the opposite ends of the cylinder for connecting the same with the inner casing, the cylinder and upper flange having a plurality of minute openings therein disposed above the openings in the said inner casing, a plu- V rality of equi-distantlv spaced concavo-c0nvex perforated disks. and means for holding the disks in properly spaced position within the said inner casing above the said cylinder.
